LOCOMOTIVE-TENDEIL Specication of Letters Patent.

Patented Aug. 5, 1919.

To all whom t may concern.'

Be it known that I EDWARD RYAN, a citizen of the United SZtates, and resident of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Locomotive-Tenders, of which the` following is a specification and which are illustrated in the Iaccompanying drawings, forming `a part thereof.

The invention appertains to a conveying mechanism for delivering fuel from the coal bin of the tender to the stoking mechanism of a locomotive, its objects being to increase the eliiciency, strength and durability of such transferring means. l

It has been common practice to transfer the fuel by means of a screw conveyer located Ibelow the floor of the bin and extending to the rear end thereof. Because of the length of the screw it has been liable to distortion and breakage, and as the opening to its trough is considerably narrower than the bin much fuel would remain at each side throughout its entire length and would require manual labor in feeding.

The object of this invention is to provide for the use of a. much shorter screw, extending backwardly under the forward end only of the bin, means being provided for moving the fuel forwardly in the bin to the conveyer trough opening.

The invention consists in means for accomplishing this result, and more specifically in the operative connection of such means with the screw.

A preferred embodiment of the invention is hereinafter described, and is illustrated in the accompanyin drawings in which- Figure 1 is a etail vertical longitudinal section of a tender and of the rear end of the locomotive;

- Fig. 2 is a detail plan view, partly insection, on the line 2-2 of Fig. 1;

Fig. 3 is a detail sectional view on the line 3-3 of Fig. 1';

Fig. 4 is a detail section on the line 4 4 of Fig. 1; and

Fig. 5 is a detail plan of the fuel bin and of the fuel pusher mounted on the door thereof.

The rear end or cab of a locomotive is represented Iat 10, and the back wall of its fire-box at 11. At 12 there is shown one form of Stoker mechanism provided with a suitable motor, as 13.

The forward end of a tender is represented at 14, the floor of its fuel bin being shown at 15 and the rear wall or slope sheet of the fuel bin at 16. A screw conveyer17, mounted in a suitable trough 18 below the floor 15, extends forwardly and delivers into the receiving chamber 19 of the Stoker mechanism, this screw being driven from the engine 13 by means of a sprocket wheel 20, secured to a short shaft section 21, connected to the screw shaft by means of a universal joint 22, as is usual in devices of this character. The rear end of the shaft 23 of the screw is journaled i in and extends through a suitable bracket 24, secured below the tender floor.

The conveyer screw 17 extends but a short distance under the floor of the bin, and its trough is supplied with fuel through an opening 25 in this floor.

A fuel pusher,.here shown as comprising two pusher heads 26, 27, in tandem arrangement and rigidly secured together, reciprocates over the rear portion of the floor 15 of the fuel bin for the purpose of advancing the fuel to the opening 25. This pusher may be actuated by power derived from any suitablesource and transmitted by any suitable means. More specifically, it may be driven by a suitable connection with the shaft 23 of the conveyer screw, and such an arrangement is shown in the drawings and constitutes a feature of this invention.-

For the purpose of operatively connecting the pusher with the conveyer shaft, there is provided suitable transmitting gear mounted in a frame 28 secured below the rearward portion of the floor 15. This power-transmitting mechanism comprises a short shaft 29 in alinement with the shaft 23, a suitable clutch, as, 30, being provided for connecting it therewith, this clutch being operatedfby means of a shipper lever 31, controlled by a4 Ahand crank 32 preferably located at the front end of the tender and mounted on a vertical shaft 33, which extends below the i floor of the tender and is provided at its lower end with a crank arm 34, connected to the shipper lever 31 by means of a link 35.

A'beveled pinion 36, fixed on the rear end of the shaft 29, meshes with a beveled pinion 37 mounted on a vertical shaft 38, which shaft carries at its upper end a spur pinion 39. meshing with a spur gear 40 mounted on a vertical shaft 41. The gear 40 is pro- 'Shaft 29 with the shaft 23, the pusher is caused to reciprocate. The rearward faces of its heads being inclined, it travels under the fuel on its backward movement, and the forward faces of these' heads being substantially vertical the fuel is carried with it on the forward movement and advanced to the opening 25, through which it falls into the conveyer trough and is then carried forward by the screw. When the fuel feed is too rapid the pusher is thrown out of action by disconnecting the clutch.

As the pusher heads may extend entirely across the floor of the bin, the entire load of fuelmay beftransferred tothe proximity of the comparatively short feed opening, and practically the entire supply is thus mechanically delivered to the Stoker.

The slot within which the stud 44 travels is covered by the pusher, a forwardly 'projecting apron 45 being provided for coverin the slot upon the recession of the pusher.

ile the construction shown and described is preferred, various changes and modifications therein may be made without departing from the scope of the invention.

I claim as my invention: 1. In alocomotive tender having a fuel bln, in comblnatlon, a fuel conveyer located below the fuel bin and receiving therefrom and leading forwardly, and means in the bin for advancing fuel to the receiving end of the conveyer..l

2. In a locomotive tender having a fuel bin, in combination, a fuel conveyer located below the fuel bin' and receiving therefrom, and leading forwardly, and a reciprocating fuel pusher in the bin for advancing fuel to the receiving end of the conveyer.

3. In a locomotive tenderl having a fuel bin, in combination, a power actuated fuel conveyer'located below the floor of the bin,

and recelving therethrough, a fuel pusher for advancing fuel to the receiving end of the conveyer, and operative connection between the conveyer and pusher.

4. In a locomotive tender having a fuel bin, in combination, a power actuated fuel screw conveyer located below the lioor of the bin, and receiving therethrough, a fuel pusher for advancing fuel to the receiving endof the conveyer, and operative connection between the conveyer and pusher.

5. In a locomotive tender having a fuel bin, in combination, a power actuated fuel conveyer located below the floor of the bin, and receiving therethrough, a fuel pusher for advancing fuel to the receiving end of the conveyer, and operative connection between the conveyer and pusher, and a means for breaking such connection.

6. In a locomotive tender having' a fuel bin, a power actuated fuel conveyer located below the floor of the bin and receiving therethrough, 4a fuel pusher for advancing fuel to the receiving end of the conveyer, and a train of gears connecting the conveyer and pusher.

7. In a locomotive tender having a fuel bin, in combination, a spiral conveyer located below the floor of the bin and receiving therethrough, a reciprocating fuel pusher in the bin and deli-vering to the receiving end of the conveyer, a crank, a pin connecting the crank and pusher, and gears for driving the crank from the shaft of the conveyer.

8. In a locomotive tender having a fuel bin, in combination, a spiral fuel conveyer below the floor of the bin, and receivingl therethrough, a bearing frame back of the conveyer, a gear shaft journaled in the frame, a clutch separably connecting the shaft to the conveyer shaft, a reciprocating fuel pusher in the bin delivering to the conveyer, a crank wheel in geared connection with the gear shaft, and a pitman connecting the crank Wheel and pusher.

9. In a locomotive tender having a fuel bin, in combination, a fuel conveyer located below the ioor of the bin and receiving fuel through an aperture in such floor and leading forwardly, and a reciprocating fuel pusher traveling over the floor of thebin for advancing fuel to the floor of the aperture without restricting thefeffective size of such aperture.
